Firebug throws the following error:
__doPostBack is not defined
[Break On This Error] "OK": function () { __doPostBa...ID, ''); $(this).dialog("close"); },

I have spent days looking at different jQuery confirmation box examples but this is the best I can do. Ideally I would want to be use http://jqueryui.com/demos/dialog/#modal-confirmation within gridviews, dataViews and ListViews but can't find examples which exactly provide steps to follow.

I have created a .aspx page that contains a web form. The information in the form is submitted to a companies web site and once accepted is manipulated by the company.
